AI Technical Summary

Technical Problem

In existing technologies, when boiler filters are used for a long time, dust particles will adhere to the surface of the filter screen, causing the filter screen to become clogged, affecting the filtration efficiency and resulting in poor flue gas flow.

Method used

A boiler regenerator including a regenerator shell, heat exchange coil, exhaust pipe and inlet pipe is designed. The motor drives the rotating shaft and bolt scraper to scrape off the dust attached to the filter plate and collect it into the collection box. The filter mechanism is cleaned regularly.

Benefits of technology

It effectively prevents filter clogging, ensures smooth flue gas flow, and improves the boiler's thermal efficiency and operational stability.
